Hello I have a small problem I bought a new computer about 1 month ago for casual use however recently I have been wanting to use it for casual gaming nothing serious like crysis or cod just portal,oblivion ect. However I haven't been able to run a few games as my graphics card isn't brilliant. When I was looking for a new one I realised my psu doesn't have enough power to run a new graphics card and I have no idea on how to tell if my computer is compatible with this psu or if it will fit in the case so I was wondering if you could help me. Are these Psu and graphics cards good? Will this psu work in my computer and will it fit? Will the graphics card work in my computer?
